Note: You might need to create a dockerhub credential secret to make this demo work.

kubectl create secret docker-registry regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>

where:
<your-registry-server> is your Private Docker Registry FQDN. (E.g., https://index.docker.io/v1 for DockerHub)
<your-name> is your Docker username.
<your-pword> is your Docker password.
<your-email> is your Docker email.
